Beware superstitious friends: It's Friday the 13th again! Here are some fun facts about the day you might not know:

Apple Inc. will establish a command center for its global operations in Mesa, Ariz., promising a $2 billion investment over the next 30 years, state officials announced Monday.

Oh my gosh! The world’s first holographic computing platform! Is this or is this not the best thing ever?

Microsoft's wide-ranging announcements today about Windows 10 covered things as mundane as new customizations for the Windows 10 Start screen and as mind-blowing as a new computing holographic platform.

Apple's iPhone 6 and 6 Plus continued on a sales tear in November, prompting a surge in iOS's smartphone user share in all but one of the countries monitored by Kantar Worldpanel Comtech, the research firm said today.

A senior U.S. lawmaker wants Sony Pictures Entertainment to provide details about its recent data breach and its cybersecurity practices, saying the information will help Congress decide whether new laws are needed.

Australian businesses and government agencies will now be able to report online security incidents via the Australian Cyber Security Centre (ACSC).

The ACSC was opened last month in Canberra, and brings together online security capabilities from across the federal government into a single location.
